About this study
This study is a Delphi-based expert consensus project aimed at developing evidence-informed recommendations for photoprotection practices across various populations, including general, at-risk, and special groups (e.g., children, pregnant women, patients with photodermatoses). Despite extensive evidence on the importance of sun protection, there is variability in clinical advice regarding sunscreen selection, application frequency, SPF requirements, adjunctive protective measures, and patient counseling.
Read the detailed description
This study is a non-interventional, methodological Delphi consensus project designed to develop standardized recommendations for photoprotection practices. Photoprotection encompasses strategies to minimize ultraviolet (UV)-related skin damage, including sunscreen use, clothing, behavioral measures, and patient education. Despite broad awareness campaigns, inconsistencies exist regarding SPF selection, application methods, timing, reapplication frequency, and the use of additional protective measures.
A steering committee of dermatologists and photoprotection experts will conduct a literature review and draft initial statements addressing key domains:
Sunscreen use: SPF level, spectrum coverage (UVA/UVB), formulation (chemical vs. physical), water resistance.
Application guidelines: Amount, timing before sun exposure, reapplication frequency, body coverage.
Adjunctive measures: Protective clothing, hats, sunglasses, shade-seeking behavior.
Special populations: Children, pregnant women, outdoor workers, patients with photosensitive dermatoses.
Behavioral counseling: Education strategies, adherence promotion, and misconceptions.
Integration with skin care and aesthetic practices.
A panel of experts in dermatology, photobiology, and related fields will participate in multiple Delphi rounds. Panelists will rate agreement with each statement using a Likert scale. Anonymized feedback will be provided after each round, and statements not reaching a predefined consensus threshold (e.g., ≥70-80%) will be revised and re-evaluated in subsequent rounds.
The final output will consist of consensus-based recommendations reflecting practical, safe, and evidence-informed photoprotection practices. Areas of disagreement or uncertainty will also be highlighted, identifying research gaps and priorities for future studies.

The primary outcome is the main question the study is designed to answer.
Primary Outcome
Level of expert consensus on statements regarding photoprotection practices, measured as the proportion of panelists reaching the predefined agreement threshold (e.g., ≥70-80%) per statement across Delphi rounds.
Measured: 6-12 weeks
Secondary outcomes (1)
Secondary Outcomes
Consensus on sunscreen use: SPF level, broad-spectrum coverage, formulation, and water resistance.
